How To Use Earphones

BOJ earphones are NOT worn in the same style as headphones or standard earbuds. To enjoy the superior sound isolation and audio quality of your earphones, it is very important to get a proper fit!

Situating the Cables

Note the difference between the right (R) and left (L) earphones and insert earphone into each ear

Wrap the earphone cord over the top and down the back of the ear -- the earphone cord can also be worn hanging straight down (see figs. 1 and 2 below)

Use the adjustment tube to secure the cables either behind your head or in front


Fig. 1: Three popular methods for wearing the earphones

Inserting the Earphones

To insert the earphone, pull the ear upward and outward to straighten out the ear canal. If using foams sleeves, gently compress the foam with your fingers and insert the earphone into your ear.

Creating Your Personal Fit

The quality of the frequency response and sound isolation depends on how well the sleeves seal. If the earphone seems to be lacking in bass, check the tightness of the seal between the earphone and your ear, or try one of the other sleeve options. Each earphone comes with a selection of sleeve options. Sleeves options vary by earphone model.

We recommend taking some time to experiment with your fit kit to find the sleeve and style of wear that works best for you.


Additional Earphone Care and Maintenance
•Clean your sleeves regularly with a mild antiseptic or soapy water
•Always remove the sleeve from the earphone nozzle before cleaning
•Flex, Ultra-soft flex, and Triple-flange sleeves should be cleaned with an antiseptic routinely and when sharing
•Foam sleeves should be disposed of and replaced when they get dirty
•Wipe down the earphone housing and cable with an antiseptic routinely
•Stop using the earphones if they are causing you discomfort


Important Safety Information
•Never wear earphones while operating a motor vehicle. It may create a hazard and is illegal in many areas
•Use caution when wearing earphones while walking, jogging, cycling, etc.
•Avoid using earphones at high volume levels -- BOJ earphones are designed to provide increased listening enjoyment at lower levels
